Madhu - You might be aware that when you have common keys across dimensions, circular references will be formed... so the best example is have two tables, one with 100 rows and another with 2/3 rows of data and form a circular reference.

What you can observe with a circular reference is, your query may get data from table2 which has less rows and actually you might expect the result from table1 where you have good data.. because of loosely connected tables
